ABSTRACT

Background/Aims@#Colorectal cancer (CRC) patients often exhibit peritoneal metastasis, which negatively impacts their prognosis. CD31 and D2-40 have recently been suggested to be predictors of breast cancer prognosis, but their role in colorectal peritoneal metastasis (CRPM) remains unknown. @*Methods@#The expression profiles of CD31 and D2-40 were analyzed in CRC patients with or without CRPM and in CRC cell lines with increasing metastatic potential. Overexpression and short hairpin RNA knockdown assays were performed in CRC cells, and the effects of these alterations on epithelial-mesenchymal transition (EMT) in vitro, growth of xenograft tumors in vivo, and peritoneal metastasis potential in a mouse model of CRPM were examined. @*Results@#The expressions of CD31 and D2-40 were upregulated in CRC tumor tissues and was elevated further in tumor tissues from patients with CRPM. CD31 and D2-40 expression levels exhibited increasing trends parallel to the EMT potential of CRC cells. CD31 and D2-40 are essential for CRC cell EMT in vitro as well as for xenograft tumor growth and peritoneal metastasis in vivo. @*Conclusions@#CD31 and D2-40 contribute to CRPM by promoting EMT and may serve as prognostic markers and therapeutic targets for CRC, particularly in patients with peritoneal metastasis.

ABSTRACT

Objective The objective of this study was to evaluate the prognostic value of postoperative prognostic nutritional index(p-PNI)in the prognosis of colorectal cancer patients.Methods Retrospective analytical cases came from 89 patients with radical resection of colorectal cancer confirmed by the pathological section in Nanjing Drum Tower Hospital Suqian City People's Hospital from August 2009 to August 2012.The p-PNI was calculated based on the results of blood routine and biochemical tests after the first visit to the hospital.The Youden index was calculated using the receiver operating characteristic curve(ROC),and the PNI value combined with the best sensitivity and specificity was used as the threshold for the PNI packet.Kaplan-Meier method was used to study the effect of p-PNI on postoperative prognosis of patients with colorectal cancer.Cox regression model was selected to study the effect of p-PNI on the prognosis of colorectal cancer patients after surgery.Results The p-PNI of 89 cases of colorectal cancer patients was 25.18~60.74(43.81±6.47).The p-PNI in patients(less than 70 years old)was significantly increased when the number of lymph node metastases was less than 4,the preoperative CEA was less than 5ng/mL,and the intraoperative hemorrhage was less than 150 mL(P<0.05).When the p-PNI value was 43,the Youden exponent was the largest.Data analysis showed that p-PNI was correlated with age,lymph node metastasis,intraoperative blood loss and preoperative CEA(P<0.05).The survival rate of patients with high p-PNI was higher than that of low p-PNI group(X2=15.639,P<0.001).Single factor and multivariate analysis confirmed that p-PNI was an independent factor in the prognosis of patients with colorectal cancer(HR=2.179,95% CI:1.057~3.561,P<0.001).Conclusion p-PNI is an independent prognostic factor in patients with colorectal cancer,which is associated with long-term prognosis after surgery.

ABSTRACT

Objective To investigate the risk factors, treatment methods and significance of the cervical venous angle lymph node metastasis in differentiated thyroid cancer. Methods The clinical data of 222 patients with thyroid papillary carcinoma from December 2012 to January 2014 were collected. The surgical methods, complications and postoperative complications and pathology were analyzed. Results Lymph node metastasis was found in 133 cases. when VI lymph node was positive , the lateral cervical lymph node positive rate was 43%(57/133) inⅡDistrict, 54%(72/133) inⅢDistrict,ⅣDistrict 45%(60/133) inⅣDistrict, 60%(80/133) in jugular angle, and 6%(8/133) in V District. The levels of bleeding volume, operation time and hospitalization time in functional neck dissection (FND) group were significantly higher than those in anterior cervical muscle group and reserved anterior cervical muscle group (P<0.05). Single factor analysis showed that diameter of the tumors, thyroid membrane invasion and central region lymph node metastasis had correlations with venous angle lymph metastasis (P<0.01). Logistic regression analysis showed that thyroid membrane invasion (OR=3.539), central region lymph node metastasis (OR = 1.617), diameters of the tumors (OR = 1.321)were the risk factors of cervical venous angle lymph node metastasis. Conclusions Patients with tumor diameter equal to or more than 1.5 cm, thyroid membrane invasion and lymph node metastasis number greater than or equal to 2 should be performed with lateral neck lymph node dissection. Also the venous angle lymph node dissection should be done in these patients so as to increase radical rate.

ABSTRACT

Platelet-activation factor (PAF), one of the potent proinflammatory mediators, is produced from a large range of cells, including polymorphonuclear neutrophils, monocytes, and natural killer cells. To study the role of PAF in the pathogenesis of silicosis, we determined the PAF in silicotic patients and in healthy persons. The results showed that the concentration of PAF in the plasma of silicotic patients was significantly higher than that of healthy persons. Our in vitro experimental results showed that the total numbers of fibroblasts were markedly raised with added PAF from 0 to 1 μ g/ml. Adding 1 μ g/ml PAF significantly increased the total numbers of fibroblasts after culture for 48, 72, 96 hrs. Therefore, we suggest that PAF be possibly involved in the pathogenesis of silicosis. However, the mechanism remains to be further elucidated.
